You may have heard about the term rotary vane pump. You may have one or more in your company. It is a device that has several uses and applications. Industries like the power sector, oil, and gas, manufacturing, and semiconductor production use the technology of rotary vane pumps in their various operations and processes.
Here is a closer look at the components of a rotary vane pump.
A rotary vane system can be oil-less or lubricated. The main difference is that with lubricated rotary vane pumps, the whole system is oil-sealed to protect the components of the pump. On the other hand, oil-less pumps do not need an oil reservoir to encapsulate the parts with oil because the parts can function efficiently without any oil cooling the components.
The rotary vane vacuum pump is a rotary displacement pump. It consists of a metal housing, a durable rotor, rotary vanes, valves, working chamber, and receiver.
The metal housing may have different shapes and sizes depending on the capacity of the vacuum system. It should be robust to accommodate small to large volumes and can sustain vacuum pressures of 29.92” Hg maximum.
The rotor is a hub that is part of an electromagnetic system which rotates due to the changes and interaction of the windings and the magnetic field. The alternating current energizes the stator which produces a rotating magnetic flux. The event between the magnetic flux and the current produces a torque which makes the rotor move depending on the placement of the conductors.
Rotary Vanes and working chamber
The rotating vanes along with the rotor rotates inside the working chamber. The vanes divide the chamber into two compartments. Vacuum is created when the gas flows from the inlet valve and compressed inside the chamber as it closed by the rotary vanes.
The receiver can be vertical or horizontal depending on the specifications of the system. It contains a sight glass and a drain valve for easy maintenance and removal of pressure and content.
